WHO will launch a package of measures, the Global Scales for Early Development (GSED), to monitor the development of young children at population level up to three years of age.

The internationally validated GSED methodology provides a new common unit to measure development, much as centimetres do for height and kilograms for weight, to give an overall picture of children’s development which can be tracked over time.

The GSED aims to help countries, programmes and researchers gather and use data on early childhood development to better invest in services and support needed for young children and their families.
